To all whom it may concern vBeit known that we, JOEL J. DYE and WILLIAM A. LUCAS, citizens of the United States, residing in Newark, New Jersey,

have` invented certain new 4and useful Im'- provements in Outlets for Acid-Receptacles, of which the following is a specification.

.r The invention aims to provide an improved outlet for acid ccncentrators or other receptacles and especially for receptacles made of brickwork or the like. Mpst acid coneentrators have outlets consisting "of ordinary Apipes 'with flanges which are bolted to the wall ofthe concentrator, with interposed gaskets or packing material. This method, and in fact all methods in which het acid runs directly over the gasketsof the joints, arel very unsatisfactory.` The gaskets are soon deteriorated by thev The accompanying drawings illustrate.

an embodiment .of the invention.

Figures 1 and 2 lare diagrammatic sections. horizontal and vertical respectively, of an acid concentrator;

Fi 3 is an enlarged vertical section (on the llne 3-3 ofifige) showing one of the outlets;. `4 v Fig. L is a. plan of the two outlets;

Fig. 5 is a section on the line 5-5 of Fig. 4.

Referring to the embodiment ofthe 1nvention illustrated, the concentrator has side walls A, end walls B and aroof C made of refractory material (Fig. 2). Two practically identical outlets are illustrated, so`

that either may be used while the other is @ne `outlet takes the acid through the lower end of a side wall A and the other through suitable openings in the end wall B. Except for the difference in direction of thepassages leading to the gates hereinafter described the two outlets are identical. The tank is constructed as shownjin Fig. 3 of a lead trough D on which is an insulating or packing layer 'E anda course. or several coursesof brickwork F finished off with a flooringof tiles G. This floor. structure is extended continuously under the passage H throughv the wall of the concentrator and is extended beyond the latter to carry the gateway `by which the flow of acid t0 the outlet pipe can be stopped. The projecting portion of the floor is supportedl on a steel support or bracket comprising a floor `portion J resting on thefoundation` K of the concentrator and provided with aflangev L bearing yagainst the face of said foundation, and and'side walls comprising a front wall M N, the latter being also flanged and fastened to the usual steel bracing of channel beams N or to any other convenient part of the concentrator. This steel support carries not only the projecting floorbut the entire outlet box. The latter consists of a block O of brickwo'rk or other refractory material with the passageway through it communieating with the passage H through the wall of the coneentrator, the bottom of this passage being closed 'bythe extended floor structure of the eoncentrator and the top of this. passage being open except for a removable coverP (Fig. 8) of tile or the like.

At its outlet end the aforesaid passage coni- Inunlcates with the outlet boX hereinafter referred to. The block of brickwork for1ning the outlet boX is surrounded on its front face and on its side faces by the lead and packing sheets D and E which are bent up from the underside, extend clear to the top, the lead sheet Dbeing flanged over the upper edge of the brickwork as shown in Figs. 3 andi. The brickwork lining or boX O-is formed with two pairs of vertical grooves material to make .a tight closure if this i j should be necessary, though ordinarily a luting in` the grooves Q and R around the edges of the gates will be sufficient to prevent seepage of acid. Q.

lThe cover P serves to prevent the escape of gas. The holes in the cover through which the gates S and T pass, `should be sealed with sand or other packingmaterial.

Andwhen the gates are withdrawn to permit the passage of acid, a solid cover may 4be substituted in place of P; a luting of any sort may' ber'placed under the margin -ofthe icev lio

the brickwork on the lead casing on the cover to prevent the escape of gas under the same.

The outlet pipe V. ismade of acid-proof 'iron with a flange W located some distance beyond the inlet end of the pipe, the inlet endl X extending through an openmgfin the iront wall O of the brickoutlet box or boot .and the flange W being bolted to a flange Y on'the end; of a tubular extension Z of the lead casing D. A tubular packing 2 is located between the pipe von the one hand, and

other and has afiange between the flanges W and Y. An iron ringi is located back of the'lead ii'ange'Y to take the pressure of the heads of theseveral bolts 4. The several iangeslreferred to ,are notched as shown in Fig. lso that the bolts can be loosened and direction By this rapidly withdrawn in aradial when the joint is .to be broken.

4method of'v attachment ofthe pipe. the acid will not come in direct running contact with the gasket between the iizfinges` and Willnot tion ol the-horizontal andvertical parts is provided with a hand hole 5 surrounded by abell flange and normally closed'by a plate Gzwith'paste or luting around the edges. .O n

removing the plate arod or other instrui ment can be passed Athroughthe horizontal and vertical portions of thcpipe to clean the same.

In Fig. 1.' one of the outlet boots or boxes is indicated at O and the other at O. The

flatter is arranged with the passagethrough it at right angles to the. passage. il through which the acid passes Afrom the couccntratcrto the box; and there ,are tivo of these passagesH leading to this box. The'tvvo pipes V frm the respective yboxes O and O dis charge into a common chute or vessel 7 `which is preferably j of -brick'with a. lead A'casing like the boxes'iO-and O and which vdischarges throughap ipe (Fig. 2f) l into a cooler 9.

mally The acid-l in' the. concentrator .stands norat labout the level indicated in Fig. 3.

'- Consequently there is a seal of thev liquid l -v acid between the Haine or hot air within thev concntlatorf and the pipe 'and .j oin ts outside,
